Terrestrial, medium-sized: rhizomes 2.2-4 cm diameter, decumbent to erect.
Leaves
Fronds 35-120 cm long, nearly always proliferous on upper rachises; stipe dark brown, sparsely scaly at base, scales linear-lanceolate to narrowly deltate, brown to reddish brown, acuminate, soon deciduous; blade 1-pinnate-pinnatifid to 1-pinnate-pinnatisect, linear-triangular, glabrous, acuminate, not or only minimally narrowed at base; pinnae to 30 pairs, sessile or nearly so, alternate to subopposite, deeply lobed, sometimes proliferous near tips, basal pinnae not or only slightly smaller than next distal pinnae; ultimate segments perpendicular or slightly oblique to costae.
Sori
Sori submarginal, marginal and short-linear, or extending beyond margins, hooked to globose; indusia linear, submarginal to marginal, or cup-shaped when projecting from margins.
Notes
Latin prolifer, fruitful, productive, alluding to the proliferations on the tips of the fronds and often on the pinnae.
